Inductive Sensor M18, NPN NO, Flush – PRD18-7DN
DESCRIPTION
Autonics inductive proximity sensor PRD18-7DN
Cylindrical, NPN Normally Open, Cable Type
The PRD18-7DN inductive proximity sensor features long sensing distances and excellent noise immunity with a specialized sensor IC developed by Autonics. The connector type sensor offers easier maintenance and wiring work. This high performance cylindrical inductive sensor can be used in diverse applications requiring non-contact detection of metallic objects. The PRD18-7DN is available in DC 3-wire type.
As a quick report, this cylindrical inductive sensor provides:
- shield (flush) installation
- 18 mm sensing side diameter
- 3-wire cable connection
- Simple operation, reliable performance, and high durability
- Operation indicator (red LED)
- Durable and reliable alternative to micro switches and limit switches
- Built-in surge protection circuit
- Built-in overcurrent protection circuit
- Built-in reverse polarity protection circuit
Body
The PRD18-7DN long body size case is made of nickel-plated brass, its washer is made of nickel-plated iron, and the material of its sensing side is PBT.
Protection structure of this proximity sensor is IP67 (IEC standard).
This sensor has a red LED as the operation indicator on its body.
Connection
Connection of the PRD18-7DN is Cable Type, which contains a cable covering its 3 wires. This standard cable is black and made of PVC.
Sensing specifications
The diameter of the PRD18-7DN sensing side is 18 mm. This inductive proximity sensor detects its standard sensing target in 7 mm, this distance is called its sensing distance. Although almost no one talks about the setting distance of an inductive sensor, it should be announced that for this sensor, it is 0 to 4.9 mm.
Also, it should always be considered that this data is reported for the secure and standard sensing target, which is an 20x20x1 mm piece made of iron, for this product.
Control output
The control output of the case study proximity sensor is NPN Normally Open.
Temperature
There are limitations in environment temperature and humidity in which PRD18-7DN proximity sensor is used:
- Ambient temperature: -25 … 70°C
- Ambient humidity: 35 to 95%RH
- Storage temperature: -30 … 80°C
- Storage humidity: 35 to 95%RH
Environment resistance is rated at no freezing or condensation.
It’s better not to use this product outside of these ranges, in order to keep it stable.
